3 CONTEXT The automotive industry change quickly due to : New Technologies Regulation constraints consumer expectations J. Beretta/PSA3

4 CONTEXT Electricity,electronic and embedded software replace the majors mechanical and hydraulic components (steeringwheels, brake systems, suspension ) All the car parts come intelligent All components become networked and additional functions will be available via software Global Chassis Control, X by wire,. The communication and associate services appear J. Beretta/PSA4

5 an exemple : TELEMATICS Car audio Visio conference Telediagnostic... Mobile office Telematic covers all information exchanges between the car and the external world HF Card GPS Internet Call Center Handy phone TV J. Beretta/PSA5

6 CONTEXT Automotive Electricity and Electronic level of penetration 35 Electricity Genesee of automotive electronic electronic Proliferation Integration and maturity of electric& electronic systems Entraitement, EMV % of vehicle cost lights, radio, starter, dynamo Electronic ignition Alternator Electronic injection Speed control Telematic, starter-alternator Energie management Multiplex systems,abs, Power Train J. Beretta/PSA6

7 CONTEXT Product development Cycle: Auto motive 5 years TV, 2 years Video, Computers 1year Mobile phone : 3 to 6 moths J. Beretta/PSA7

8 THE EMBEDDED SYSTEMS FONCTIONAL INTEGRATION OF VEHICULE FONCTION : automatic windscreen wiper - Power alimentation & distribution - Control / sensors / actuators - electronic Control : microprocessor / hardware interfaces / basic software / application software Power Vehicle speed Control Rain sensor key Windscreen wiper Function N 1 Function N 2 Microcontroleur Software Power Distribution J. Beretta/PSA8

9 THE EMBEDDED SYSTEMS THE NETWORK Control screen Chassis Body Powertrain Gateway (virtual or physical) Telematics etc. J. Beretta/PSA9

10 THE EMBEDDED SYSTEMS DESGIN Body Functions Chassis Functions Navigation Cellular Phone Stereo/CD GPS Telematic Bus Display Climate control Airbag Body Safety bus Comfort Bus Plip lighting ECU Suspension Transmission Vehicle Safety bus ABS Chassis Control Communications/Data Global Positioning Electronic Toll Collection Collision Avoidance Vehicle ID Tracking SW Architecture Performance Modeling Network Design/Analysis Function / Protocol Validation Supplier Chain Integration Unit Testing & Verification RTL Coding & Synthesis SW Application Development SW Driver Development J. Beretta/PSA10

11 THE EMBEDDED SYSTEMS New functions : CONTRAINTS consequences: electric actuators - Accelerator - brakes - gear box - steering wheel. Comfort - automatic access - automatic Climate control. Safety - Airbag intelligent - crash - emergency call. Telematics - Telephone - Assistance et diagnostic - Internet. Multimedia - Audio - Video - Navigation. INFORMATION FLOW SAFETY REPONSE TIME INFRASTRUCTURE MICRO CONTROLLER POWER J. Beretta/PSA11

12 THE FUTURE o o Increasing the number of microcontrollers Optimisation of architecture, interfaces and functions standardisation is the drive for cost cutting Increasing the function links(esp, CGC, ABS, ) Structuring control algorithms o Increasing the complexity (X by wire, ) Management of safety functions. J. Beretta/PSA12

14 THE FUTURE to organise architecture UCE Car Body Spy UCE Power train 1 OEM S Bus high speed 2 UCE Telematiic UCE ICE UCE AGB Bus low speedt supplier's 3 actuators... actuators... ABS ESP J. Beretta/PSA14

15 THE FUTURE Networks Safety X by WIRE TTP BUS Simples safes CAN L.S. VAN 4.0 CAN H.S. Flexray SI Bus MULTIMEDIA / TELEMATICS D2B MOST USB communication protocols Information flow J. Beretta/PSA15

16 THE FUTURE Increasing the code The software Memory size A340 =?? A330 = 12 Mo MULTIMEDIA 10Mo 1Mo 100Ko A300 = 23 Ko A320 = 5 Mo Airbus Automotive. 607 Peugeot = 2 Mo. 10Ko 1Ko CX Citroën = 1,1 Ko J. Beretta/PSA16

17 THE FUTURE Software architecture Standardizing software host structure and components : to save time and money during car design - maximise software re-using - minimise software development effort to provide vehicle differentiation by appropriate selection of : - software components configuration - software components combination J. Beretta/PSA17

18 THE WIRE SYSTEMS Decrease the number of Wires Decreasing the number of node Decreasing the costs Increasing the multiplex: number of wires evolution: Peugeot Peugeot % SMART CONNECTORS POWER LIGNE COMMUNICATION J. Beretta/PSA18

19 THE WIRE SYSTEMS Decrease the number of Wires Smart Connector Data Ground Power Vehicle Device Electronics Network Protocol Power Switching A/D Network Interface Speed : 20 Kb/s Device Interface Smart Device Network Interface Electronics Network Protocol Power Switching A/D Vehicle Device Device Interface Smart connector harness (Delphi) J. Beretta/PSA19

20 THE WIRE SYSTEMS Decrease the number of Wires Data Bus Power line communication Power Part. 1 Part. 2 Power & Data Bus Part. 1 Part. 2 2 wire instead of 8 to 10 J. Beretta/PSA20

21 THE WIRELESS SYSTEMS Telematics Technology Infrared Bluetooth IEE b IEE a Frequency Optical 2,4 Ghz 2,4 Ghz 5 Ghz Transfer rate 115 kb/s to 4 Mb/s 721 kb/s to 2 Mb/s 11 Mb/s 54 Mb/s J. Beretta/PSA21

22 THE WIRELESS SYSTEMS Comfort Application Technologies Door Plip Optical / HF Electronic Key HF Navigation & Information GPS GSM Systems J. Beretta/PSA22

23 MANAGING THE ELECTRONIC AUTOMOTIVE TECHNOLOGY THE ELECTRONICS COMPONENT CHANGE EVERY 3 YEARS BUT AUTOMOTIVE REQUIREMENTS ARE: Reliability The electronic paradox + 10 years maintenance Operating environments Hostile conditions Product development cycle 3 5 years Cost Ultra low cost J. Beretta/PSA23

24 MANAGING THE ELECTRONIC AUTOMOVE TECHNOLOGY This mutation is possible only if we redefine the jobs of actors : Sharing development and responsibilities FONDEUR de silicon SUPPLIERS Rank 2 Hard Development & industrialisation SUPPLIERS Rank 1 INTEGRATION components & soft TOOL CHAIN PROVIDERS OEM INTEGRATION FUNCTIONS + SOFT J. Beretta/PSA24

25 CONCLUSIONS The electric & electronic business Will influence and drive more than 90% of the innovation in automobile industry Will account for 35% of the vehicle production cost by 2010 The jobs of business actors will be redefine: OEM s,car Suppliers, Component manufacturers, silicon manufacturer, tools and services providers During the next 10 years, we will witnesst: Increasing electronic functions, best management of electric power. Decreasing the number of wire (multiplex function generalization, smart connector, ). miniaturization and hybridization of components (microcontrollers, sensors, activators). development of standard middle ware. network standardizations.
